Release Notes for RISA-3D Version 15.0.3 Enhancements/Corrections Updated the program install to improve behavior for network licenses. Improved the subscription license functionality to make it more robust. Added the ability to import a Tekla Structures model into RISA‐3D. Added "Frequencies" "Mode Shapes" topics to the Report Printing options. They were erroneously removed in V15.0.2 Improved the area load mesh to work better for odd framing situations. Corrected an un‐conservative error with the strong axis flexural strength for channels. Corrected an issue where opening a model with saved moving load results would cause a crash. Corrected an issue in the maximum tab of the Member Forces spreadsheet where the program was not giving the correct values in specific instances. Corrected an issue where the Exclude feature would not work properly in RISA‐3D in a RISAFloor/RISA‐3D integrated model. Corrected an error where base plate loads were not properly transferred from RISA‐3D to RISAConnection. Discontinued support of the 32‐bit version of the program. Version 15.0.2 Enhancements/Corrections General: Added two new tabs to the Member Forces spreadsheet to display the maximum force based on internal sections and end reactions. Major improvements to the automatic model backup functionality. Improved the STAAD import functionality to give better error messaging and better steel material defaults for unsupported values. Fixed a problem where the deflection values displayed on the cursor didn't match the Joint Deflections spreadsheet if the Magnification Factor was not set as 1.0. Corrected an issue where RISA‐3D models created members that referred back to RISAFloor for the unbraced length value. Using the Copy to Clipboard command from spreadsheets no longer copies blank cells to the clipboard. Fixed a problem where the Truss High Level Generation Tool would create web members that didn't attach properly to the chords if the Out to Out option was selected. Wall Panels: Updated the P‐little delta calculations for concrete walls to show the location along the wall where it was considered. Updated the P‐little delta calculations for concrete walls for the odd case where both axial forces and moment forces were below program minimum thresholds. Fixed a problem where the 2011 and 2013 ASD masonry code was over‐conservative in designing the in‐plane shear reinforcement spacing. Fixed a problem where the Exclude command did not work for the Wall Panel Forces spreadsheet. Fixed a conservative problem where wall force diagrams in the detail report would report a min/max of 0 even if the forces didn't go to zero. Fixed a problem with printing out‐of‐plane concrete lintel detail reports where the program would print the in‐plane report instead of the out‐of‐plane report. Fixed a automatic meshing error where perpendicular walls framing into one another were causing the internal mesh to fail. Corrected an issue in the reported masonry wall panel output to show results based on a consistent effective width. Analysis:
